DOE announces NEPA exclusion for advanced reactors
The Department of Energy has announced that it is establishing a categorical exclusion for the application of National Environmental Policy Act (NEPA) procedures to the authorization, siting, construction, operation, reauthorization, and decommissioning of advanced nuclear reactors.
According to the DOE, this significant change, which goes into effect today, “is based on the experience of DOE and other federal agencies, current technologies, regulatory requirements, and accepted industry practice.”

One of the challenging problems of magnetized target fusion (MTF) is developing ways to transport energy to the target situated at a distance far enough from the energy source so as to prevent damage to the permanent parts of the source. Several schemes were considered in the past, including the use of particle beams coupled with the inverse diode, mechanical projectiles in combination with magnetocompressional generators, and the plasma liner. In this paper, a possible modification of the original concept of the plasma liner (by Thio et al.) is described. The modification consists of creating a thin, higher-density shell made of a high-Z plasma and accelerating it onto an MTF target by the thermal pressure of hydrogen plasma with a temperature of ~10 eV. We discuss constraints on the parameters of this system and evaluate the convergence ratio that can be expected.
